O.G.P.U. Prison by Sven Hassel
The Russian uses his machine pistol like a scythe. Feldwebel remains standing for a fraction of a second. The rain of bullets pours into him, making him twitch violently. He falls to the floor. The Russian grins. There is no doubt that he is enjoying himself.
Sven Hassel and his comrades are ordered to take O.G.P.U. Prison in any way they can, even if it means killing the Russians with their bare hands.
Armed with flame-throwers and heavy artillery, the 27th Penal Regiment plan their attack.
O.G.P.U. PRISON is one of Sven Hassel's most compulsively readable novels, full of battle scenes, written in the gritty style that Hassel is renowned for.
